On August 23, scientists will mark the 20th anniversary of the National Science Foundation’s Very Large Array, the most powerful, flexible and widely-used radio telescope in the world.

Pulsars, those spinning, superdense neutron stars that send powerful lighthouse beams of radio waves and light flashing through the Universe, have been lying about their ages.

The world’s most productive and widely-used radio telescope, the National Science Foundation’s Very Large Array, can be improved tenfold with an expansion project proposed by the National Radio Astronomy Observatory.

Sophisticated computer analysis of 20 years of data from the National Science Foundation’s Very Large Array radio telescope has revealed evidence of hot bubbles in the dense, rapidly-spinning disk of material being sucked into a massive black hole 26,000 light-years distant at the heart of our own Milky Way Galaxy, astronomers announced.

A project to expand the National Science Foundation’s famed Very Large Array radio telescope has received strong endorsement from a prestigious national panel of astronomers given the task of setting priorities for astronomical projects in the next decade.

A disk of water molecules orbiting a supermassive black hole at the core of a galaxy 60 million light-years away is reverberating in response to variations in the energy output from the galaxy’s powerful central engine close to the black hole.

Scientists have discovered the closest black hole yet, a mere 1,600 light years from Earth.

A team of astronomers has revealed tantalizing new information about the explosions of massive stars, the workings of galaxies with supermassive black holes at their centers, and clusters of galaxies.

A superfast jet of subatomic particles presumably powered by the gravitational energy of a black hole has collided with nearby material, been slowed dramatically and released much of its energy in the collision, radio astronomers report.

Astronomers using radio telescopes in New Mexico and California have discovered a giant, rotating disk of material around a young, massive star, indicating that very massive stars as well as those closer to the size of the Sun may be circled by disks from which planets are thought to form.
